The ability of the eye to distinguish different colors is clearly an important source of information gathering. It has long been recognized that infrared systems would profit greatly by such an ability in areas such as target acquisition and identification, clutter and decoy rejection. No technology, however, has as yet emerged which could offer this capability at an affordable cost to most weapon systems. The present in-house program has been successful in demonstrating a new technical approach to multi-color infrared systems which is simple, straightforward and inexpensive. The new technology is based upon multilayers of thin epitaxial film detectors sandwiched in small dots, each dot being capable of detecting three or more infrared colors.
